SPECIFICATION forming part of Letters Patent No. 736,007, dated August11, 1903.

Application filed January 20, 1903. Serial No. 139.820. (No specimens.)

T0 at whom it may concern:

Be it known that we, FRITZ PERRELET and KARL BECKER, subjects of theGerman Emperor, residing and having our post-office address at24Ludwigstrasse, Offenbach-on-the Main, Germany, have invented certain newand useful Improvements in Decomposing Tallow and the Like, of which thefollowing is a specification.

The objects sought to be attained by our invention are to expedite andcheapen the decomposition of fats, to carry on the process continuouslyinstead of intermittently, as is the case where specified charges aredecomposed, to avoid the use of large metallic chambers within which todecompose the fat, and generally to improve upon the processesheretofore known.

The invention will be fully described here inafter, reference being hadto the accompanying drawing, which shows one form of apparatus'capableof decomposing fat in accordance with our improved process.

The fat may be contained in an open vessel A, from which it is forced byany suitable means, as an injector B, through a heater. In the presentcase the heater is shown as a coil J, one end of which is connected tothe injector B and the other end to a conduit a. The coil is inclosed ina casing j, provided with a steam-inlet lo and a steam-outlet Z, the

latter being connected to the injector B by a pipe m. A pipe 2' leadsfrom the injector B into the tank A. The highly-heated fat underconsiderable pressure flows through the conduit a to a nozzle 0, fromwhich it issues, preferably in a finely-divided condition, (in the formof a spray, for instance,) into a closed chamber d. The decomposingmaterial may be contained in a tank A, from whence it is forced by aninjector B into and through a coil (not shown, but similar to that inthe easingj) in a casingj and through a conduit m to a nozzle 0, whichdischarges into the chamber d. The casingj is provided with a steaminletand a steam-outlet Z, the latter being connected to the injector B byapipe m. A pipe 0) leads from the injector B into the tank Af.Highly-heated decomposing matter is forced under pressure through theconduit b to another nozzle 0', from which it issues, also preferablyin'a finely-divided condition, into the chamber d, where it becomesintimately mixed with the heated fat. The incoming currents of fat anddecomposing matterwill preferably intersect each other, and as'both areflowing under considerable pressure they will become intimately mingled,and if the proportion of fat and decomposing matter entering the chamber(1 be properly regulated the decomposition of all the fat entering thechamber d will be effected in a perfect manner. From the chamber cl thedecomposed fat will flow through a coil in the heating-chamber 6 throughthe nozzle f to a settling-tank X, where the natural separation of theglycerin will occur.

Any suitable decomposing material may be employed, as steam, cream oflime, acid, 850. While we prefer to introduce the fat and decomposingmatter into the chamber (1 in a finely-divided condition, it is notabsolutely essential. It is, however, necessary that the enter thechamber d at different points and that within the chamber they shall bebrought together with sufiicient force or violence to insure a thoroughmingling together of the particles of fat and decomposing material, and

it is also necessary in order to attain the best results that only somuch fat shall enter the chamber (1 as can be thoroughly acted on byitbeing only necessary to keep up the supply of fat and decomposingmatter, and more fat can be decomposed in a given time than in caseswhere charges of fat are decomposed and which necessarily makes theprocess intermittent.

Another advantage is that our process can be carried out without the useoflarge metallic decomposing-chambers, which are expensive and sometimesdangerous, and, further, the expense of the necessary heat required fordecomposing a given quantity of fat by our process is much less thanwould be necessary to furnish the heat required to decompose the samequantity of fat by charges in large vessels;

Having described our invention,we claim 1. The process herein describedof decomposing fats, which consists in introducing under pressure into aclosed chamber a current of fat and steam, and simultaneouslyintroducing under pressure into said chamber an independent current of adecomposing agent at a different point, and causing said currents tomeet within the chamber and become intimately mixed, and then conveyingthe mixture through a heated conduit to a separating-tank, substantiallyas set forth.

2. The process herein described of decomposing fats, which consists inintroducing under pressure into a closed chamber a current of fat andsteam, and simultaneously introducing under pressure into said chamberan independent current of steam and a decomposing material at adifierent point, and cansing said currents to meet within the chamberand become intimately mixed, and then conveying the mixture through aheated conduit toa separating-tank,substantiallyas set forth.

3. The process herein described of decomposing fats, which consists inintroducing under pressure into a closed chamber a current of fat andsteam, and simultaneously introducing under pressure into said chamberan independent current of steam and an alkaline decomposing material ata different point,and causing said currents to meet within the chamberand become intimately mixed, and then conveying the mixture through aheated conduit to a separating-tank, substantially as set forth.

4. The process herein described of decomposing fats which consists inintroducing un der pressure into a closed chamber and in the form of aspray, a current of highly-heated fat, and simultaneously introducingunder pressure into said chamber, also in the form of a spray, a currentof highly-heated decomposing material at a different point, and in adirection to intersect the incoming spray of fat and therebyintimatelymix them, and then conveying the mixture through a heated conduit to aseparating-tank, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
